Herein, an organic-inorganic hybrid solid electrolyte, formed by an organic network of poly(ethylene oxide) chains that is connected with an inorganic Si-O-Si backbone network containing lithium salt, is proposed as a new interfacial material between a garnet-type oxide solid electrolyte and high-potential cathodes. The properties of the hybrid solid electrolyte are evaluated to obtain a material that is chemically and electrochemically compatible with the solid electrolyte and active material. Thereafter, the different procedures to fabricate a low-resistance solid-solid interface between the solid electrolyte and LiCoO2 using the hybrid solid electrolyte are evaluated. The hybrid solid electrolyte provides an ionic/electronic percolation of active material particles and excellent adherence properties, thereby enabling the operation of the all-solid-state battery at room temperature to achieve a high initial discharge capacity of 125 mAh.g(-1).American Chemical Society2020-11-23engjournal articleAMhttp://hdl.handle.net/2115/83318https://doi.org/10.1021/acsaem.0c021642574-0962ACS applied energy materials3111126011268https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/83318/1/Rosero%20ACS%20applied%20energy%20materials%203%2011%202020.pdfapplication/pdf1.15 MB2020-11-23
